I was reading the man page for beep(1), and I discovered that you can beep at a set frequency and duration. Then I thought it could be possible to make a shell script to beep "music", and came across the idea that you could also even use mixer(8) to play the beeps at different volumes! I'm no good at musical stuff myself, but if anyone manages to make anything coherent out of this, then please post it here! I'm surprised that no one has discussed this before! I guess this could be the logical, even more constrained successor to chiptune on the Atari TIA, or it may just be me trying to fill time.
